1.Turn to p. 110. What is kinetic energy? What factors affect an object’s kinetic energy? 2.What happens to an object’s kinetic energy as its speed increases? 3.What happens to its kinetic energy if its mass increases? 4.P. 112. What is potential energy? Which has greater potential energy: a book lifted 1 meter off the ground or 10 meters of the ground? Why? 5.If you drop the book from 10 meters, what happens to the potential energy? Why? 6.Complete Figure 3
